Agnetha Faltskog, the blonde singer with Abba, has admitted she did not think the band "sounded or looked very good" at the height of their fame.
In her first interview for three decades, the 63-year-old said the Swedish foursome were not taught to dance on stage.
The most reclusive member of the '70s supergroup has emerged into the limelight to release a new album.
She admitted the band's dancing was nothing compared to the modern routines of stars like Lady Gaga.
"Performing live is not my favourite. Walking on stage in concert and singing live, that is a bit difficult. And I don't think we sounded or looked very good."
Agnetha said she found the attention during the height of her fame difficult.
But now she is ready to sing again and even has a track with Gary Barlow on the new album.
"It is very sexy and a good song," she said. (© Daily Telegraph, London)
